求哪位大神可以帮我看看到底是哪里错了?
#include <stdio.h> int main() { int year = 2008; int month = 8; int day = 8; int num=0; switch(month) case 1; num=0; break; case 2; num=30; break; case 3; num=59; break; case 4; num=90; break; case 5; num=120; break; case 6; num=151; break; case 7; num=181; break; case 8; num=212; break; case 9; num=243; break; case 10; num=273; break; case 11; num=304; break; case 12; num=334; break; if(year%4==0) { num+=1; } num+=day; printf("%d\n",day); return 0; }
